Versuchsvorschrift

By following a similar procedure as described in Example 1, DIBAL-H reduction of (2-bromo-4-fluoro-phenoxy)-acetic acid methyl ester, and subsequent reductive amination with isoquinoline-5-sulfonic acid (2-amino-ethyl)-amide gives the free amine of the title compound as a white foam. ESIMS: m/z 468 [(M+H)+, 79Br], 470 [(M+H)+, 81Br].
